The health sciences are, nowadays, one of the major application areas for case-based reasoning (CBR). paper presents a survey recent medical CBR systems based on literature review and an e-mail questionnaire sent to corresponding authors papers where these are presented. Some clear trends have been identified, such as multipurpose systems: more than half current address task. Research in area is growing, but most still prototypes not available market commercial products. However, many...

The extraction of relevant features from the photoplethysmography signal for estimating certain physiological parameters is a challenging task. Various feature methods have been proposed in literature. In this study, we present novel fiducial point algorithm to detect c and d points acceleration photoplethysmogram (APG), namely “CnD”. allows application various pre-processing techniques, such as filtering, smoothing, removing baseline drift; possibility calculating first, second, third...

The ubiquity of sensors in smart-homes facilitates the support independent living for older adults and enables cognitive assessment. Notably, there has been a growing interest utilizing movement traces identifying signs impairment recent years. In this study, we introduce an innovative approach to identify abnormal indoor patterns that may signal decline. This is achieved through non-intrusive integration smart-home sensors, including passive infrared embedded everyday objects. methodology...

Photoplethysmography is a non-invasive technique used for measuring several vital signs and the identification of individuals with an increased disease risk. Its principle work based on detecting changes in blood volume microvasculature skin through absorption light. The extraction relevant features from photoplethysmography signal estimating certain physiological parameters challenging task, where various feature methods have been proposed literature. In this work, we present PPGFeat, novel...

Heavy working conditions, as well sedentary behaviour, are risk factors for health. There is a lack of wearable measurement systems monitoring carried loads while walking. Pedobarography, the study force fields acting between plantar surface foot and supporting surface, supposed to be useable estimating loads. Purpose. The aim this paper present novel method selecting appropriate samples weight estimation load during walk system, based on pedobarography, consisting commercial off shelf...

Accurate pedometers are useful tools to motivate and estimate physical activity. There today free pedometer applications available for download cell phones, thus enabling measurements by a device already worn. It is important evaluate their accuracy appropriate ways wear the phone when using applications. The aim of this study was six different three worn at positions. 10 test persons performed sequences 200 steps with each application, phone, position. Only one application combination...

The aim of this study was to evaluate an integrated probe using LDF and multiple PPG, for the long-term aspects skin temperature blood flow variations at different tissue depths, especially investigate whether presence affects temperature. Measurements were performed over 60 min on lower back ten subjects, lying a mattress. surface also measured before after period, repeated with three configurations switched on, turned off in absence probe. A general increase found occur during interval all...

The aim of this pilot study was to investigate the possibility find a correlation between output from portable pedobarography system and walking intensity expressed as speed. uses shoe insoles with force sensing resistors wireless transmission data via Bluetooth. force-time integral, at toe-off phase step, for sensors in forward part right foot used measure impulse 10 subjects performing walks three different speeds. This then corrected by multiplication step frequency. indicates that shows...

Cardiovascular diseases (CVDs) are a leading cause of death worldwide, and hypertension is major risk factor for acquiring CVDs. Early detection treatment can significantly reduce the developing CVDs related complications. In this study, linear SVM machine learning model was used to classify subjects as normal or at different stages hypertension. The features combined statistical parameters derived from acceleration plethysmography waveforms clinical extracted publicly available dataset....

Today everyday life for many people contain situations that may trigger stress, or result in an individual living on increased stress level under long duration. High of over time cause serious health problems. It is known respiratory rate terms hyperventilation (defined as low pCO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) important factor and can be used the diagnosis stress-related dysfunctions. also biofeedback training but...

The aim of this work has been to develop a technical support enabling home-based motor training after stroke. basis for the plan an interactive solution supporting three different groups stroke patients: (1) patients with discharged from hospital neuro team; (2) whose team will be phased out and (3) living impaired functions long-term. technology developed in close collaboration end-users using method earlier evaluated described [12]. This paper describes main technology. Further, results...

Objectives Walking speed is an important component of movement and a predictor health in the elderly. Pedobarography, study forces acting between plantar surface foot supporting surface, approach to estimating walking even when no global positioning system signal available. The developed portable system, Identifying Velocity Load (IngVaL), cost effective alternative commercially available pedobarography systems because it only uses three force sensing resistors. In this study, IngVaL was...

Exercise physiology investigates the complex and multifaceted human body responses to physical activity (PA). The integration of electrical bioimpedance (EBI) has emerged as a valuable tool for deepening our understanding muscle during exercise.

Whiplash Associated Disorders (WAD) are several remaining symptoms after an acceleration-/deceleration injury of the neck, often due to a road accident. Common neck pain, headache, stiffness, loss sensation, memory impairment and concentration difficulties. The whiplash-related injuries were estimated cost Sweden more than SEK 4 billion 2005, main part these costs takes form compensation for income, as result incapacity work. aim this project has been develop training rehabilitation system...
